C0 WARNING AND INSTRUCTIONS
The use of the crane is reserved to authorized personnel, instructed in advance,
who has to conform to the safety norms and instructions contained in the use
manual supplied with the crane. (See norms ISO 9926-1)
It is absolutely prohibited to walk or stop under a suspended load
It is prohibited for unauthorized persons to be within the working area.
Under no circumstances interfere with the safety and protection devices.
Warning plates, as well as instruction and operation plates must be replaced
when no longer readable or missing. See Paragraph R0 Instruction and warning
plates.
Do not use the outriggers to raise the vehicle.
To avoid hitting bridges or tunnels check and record the overall height of your
crane in the folded position or in laid position in the body or on the load. Always
respect and pay proper attention to road signs placed in proximity of such
obstacles.
C0.1 Before operating
(!) ATTENTION (!)
Check that protections are in their place and that all safety devices are fitted
and active. (See norms ISO 9927-1)
Keep the ladder and the control station on the top seat, clean; the seat can tilt
forward.
Make sure that control stations are properly lit so as to ensure safety while opera-
ting and allow instruction plates to be visible.
Check that the working area is adequate and pro-
perly lighted for your crane.
Make sure that the hook is always free to rotate on
its pin and that nothing obstructs its vertical positio-
ning.
Check the efficiency of the hook safety catch.
Carefully inspect the condition of ropes or chains.
Make sure that the pallet fork is connected to the crane hook by means of a chain
having at least three (3) rings.
C0.2 During operation
Take the vehicle fumes away from the working area by fitting an extension tube of
a suitable diameter to the exhaust system.
Do not run the engine in a indoor area without first making sure there is adequate
ventilation.
When using the ladder to reach the control station on the top seat, avoid knocking
into the controls while going up or down the ladder.
The control station on the top seat is provided with side safety guards; stay within
these guards.
Make sure that no one is within the working area of the crane.
Avoid swinging the load above working and transit areas; any hidden danger
situation must be audibly alarmed.

Avoid all those situations which may result in crushing during vehicle stabilization,
crane movement and load handling.
(In conformity with EN 349 standard the minimum safe working distances
to avoid crushing parts of the body)
The table indicates the minimum safety working distances concerning the various
parts of the body.
The figures illustrate circumstances which may turn out to be dangerous if you fail
to respect the minimum safe distances and if it is impossible to introduce larger
parts of the body.
(!) ATTENTION (!)
Failure to respect the minimum safe distances may result in a safety hazard
and a deadly risk.
Remember that
the stability of
the unit (crane-
vehicle) is only
guaranteed by
the complete
lateral extension
of the outriggers
and by the observance of the capacity plates.
Stabilize the vehicle on a horizontal plane with a maxi-
mum tolerance of 1,5 degrees. Make sure that the outrig-
ger rams rest on a solid base, if necessary use larger
outrigger base plates (available on request) to avoid
sinking. If you adopt other means, make sure that they
are suitably sized for the load they must bear.
(!) ATTENTION (!)
Respect the distances di sicurezza from electric
lines; the minimum distance is, according to CEN
norms, five (5) meters, except for otherwise prescribed by national norms.

G1 TILTABLE OUTRIGGER RAMS
Outrigger rams are allowed to be stored in an inclined
position, when obstructions on the vehicle chassis prevent
their vertical stowability. These hinged supports are placed
between the outrigger supports and the rams; the fixed
part is screwed to the supports while the mobile part is
screwed to the rams. (fig. 12-12a)
To place the rams in a working condition.
- Supporting the ram, remove the check pin and the
locking pin from their positions.
- Position, carefully, the ram in working condition,
insert the locking pin in its new position and secure
it with the check pin.
To re-position the rams to the folded position.
- Remove the check pin and the locking pin.
- Position, the ram in a upward direction and
supporting the ram, insert
- the locking pin in its new position and secure
it with the check pin
(!) The locking pin is constructed from special material
- do not replace it with a non original part
- your security depends on it

G2 MANOEUVRES AND CONTROLS TO STABILIZE
THE VEHICLE
The outriggers rams prevent damaging stresses both to the frame and to the
vehicle suspensions on which the crane is mounted to and assure the stability
of the unit during load handling.
Be very careful when stabilizing the vehicle; make sure that no one is or tran-
sits in close proximity of the working area of the outriggers.
(!) ATTENTION (!)
The crane stability is maintained by the maximum extension of the outrigger
supports
, by the solidity of the base underneath the plates of the outrigger rams
and by the observance of the capacity plates. To check the maximum working
pressure see Paragraph D0.1 Technical data
Check that the outrigger rams are applied on a solid base; if necessary use
larger outrigger base plates (available on request) to avoid sinking.
When stabilization is complete the wheels of the vehicle must still be in contact
with the ground and the suspensions must not be fully unloaded.
Stabilize the crane so as to operate on a horizontal plane with a maximum
tolerance of 1,5 degrees.
While loading, it may be necessary to vertically adjust the outrigger rams to
prevent an overload on the outriggers, then stabilize again.
While unloading, the outrigger rams may not be perfectly in contact
with the ground because of a rise in the suspension; it is therefore
recommended to stabilize the vehicle during operation to avoid an
overturn.
G2.1 Supplementary beam; manual extension
of the outrigger supports
(!) ATTENTION (!)
To manoeuvre the supports hands must only grab the handles
placed on the outrigger rams.
Position the lever Bof the outrigger locking device from the
pos. 1 to the pos. 2 (released position) fig. 13.
Put the lever Aof the outrigger security check from the posi-
tion of the fig. 14 to the one of the fig. 14a.
Extend the outrigger support from the base and position the
lever B to the pos. 1.
Extend the outrigger support till the coupling of the pin of the
lever B.
By the same sequence, repeat the operations described to extend the other
support.
(!) ATTENTION (!)
The complete extension of the outrigger support is visually indicated by the yellow
triangle which is found at the end of the beam. (Fig.14b)
The outrigger support is locked in position by the security pin; this will ensure the
complete extension of the outrigger support and the impossibility of accidental
movements.
